HELENA, Mont. (AP) – A Havre businessman charged in a corruption investigation at Rocky Boy’s Indian Reservation will be sentenced in December after he pleaded guilty to failing to file currency transaction reports.

Shad Huston pleaded guilty on Thursday to not reporting financial transactions when his money service business cashed checks of more than $10,000.

Those 19 checks included money for the family members of Chippewa Cree tribal leaders who have been convicted in the corruption probe.

Prosecutors say the transaction reports are required to allow federal officials to track money laundering and fraud.

Huston, who is 40, could face up to five years in prison when U.S. District Judge Brian Morris sentences him on Dec. 16.

Huston still faces charges of bribery, wire fraud, embezzlement and false claims. He has pleaded not guilty to those charges.
